- •
Structural transitions involving shape changes play an important role in cellular physiology.
- •
Sphere-to-rod transition can be conveniently induced in charged micelles by increasing ionic strength of the medium.
- •
The process of sphere-to-rod transition in micelles is associated with profound dipolar rearrangement.
- •
The dipolar reorganization can be monitored as a change in micellar dipole potential using a potential-sensitive probe.
